“As long as justice is postponed we always stand on the verge of these darker nights of social disruption”...so said Martin Luther King Jr. in a speech on March 14, 1968, just three weeks before he was assassinated.

Salisbury poison ‘made at Russia’s Porton Down’

The Shikhany research base, 500 miles from Moscow, is thought to have produced the novichok poison. The facility also contains shops, hospitals and schools

A Russian military research base has been identified as the source of the nerve agent used at Salisbury in a British intelligence briefing for its allies, The Times has learnt.

It was used to persuade world leaders that Moscow was behind the poisoning and said that the novichok chemical was manufactured at the Shikhany facility in southwest Russia.

The briefing led to the expulsion of more than 150 Russian diplomats from 28 countries. Also included was information suggesting that Shikhany, Russia’s equivalent of the defence laboratory at Porton Down, was used during the past decade to test whether novichok could be effective for assassinations abroad. The weapons-grade nerve agent was used to poison the former double agent Sergei Skripal and his daughter, Yulia, a month ago.

The stockpiles detected at Shikhany were far smaller than would be used in a battlefield weapon, suggesting their use in targeted killings. Hamish de Bretton Gordon, the former commander of Britain’s Chemical, Biological, Radiological and Nuclear Regiment, who has seen the intelligence, called it very compelling. “The intelligence Britain has clearly points to Russia and Shikhany,” he said. “No doubt the Russians are scrubbing it down as we speak.”

Mr de Bretton Gordon said that there was nothing to support claims that novichok could have come from elsewhere in the former Soviet Union, such as Ukraine or Uzbekistan.

Yesterday Ms Skripal spoke publicly for the first time since the poisoning, saying that her strength was “growing daily” in a statement released by the Metropolitan Police on her behalf.

Officials were working to determine the authenticity of a phone call broadcast by Russian state television said to be between Ms Skripal, 33, and her cousin, Viktoria. The woman said to be Ms Skripal claimed in the call that her father, 66, was also recovering, contradicting hospital reports that he is critical but stable. Russia repeated a demand yesterday that it be given consular access to the Skripals.

Britain is understood to be anxious not to reveal its sources over the briefing but intelligence services are growing frustrated at Russia’s upper hand in the propaganda war. They have lobbied Downing Street to release more of the intelligence that helped to convince allies of Moscow’s guilt. Whitehall sources said that the intelligence sharing with allies had been unprecedented.

Alexander Yakovenko, the Russian ambassador to London, insisted yesterday that his country had never developed the novichok agent. “This is a creation of some other countries and some scientists,” he said.

In a 90-minute press conference he veered from sarcasm to giggles to praise for the embassy’s notorious Twitter feed. One journalist took Mr Yakovenko to task, saying: “You keep smiling and joking. That suggests you are not taking this seriously.” “That’s just my style,” Mr Yakovenko retorted. “Don’t read too much into it. Russia is taking this very seriously.”

Britain and Russia clashed at the UN last night after Moscow called an emergency session of the security council. Vassily Nebenzia, the Russian ambassador to the UN, said: “We have told our British colleagues that you’re playing with fire and you’ll be sorry.” He demanded that Britain produce further evidence of his country’s involvement.

Karen Pierce, the British ambassador to the UN, said that Russia was like “an arsonist turned firefighter but in this particular instance the arsonist wants to investigate his own fire”.

She told Mr Nebenzia that when Britain said it was “highly likely” that Russia carried out the attack “it is a reflection of our judicial process and should not cast doubt on our certainty”. “We do not have anything to hide but we fear Russia has something to fear,” she said.

Sir Malcolm Rifkind, a former foreign secretary, told the BBC that Russian diplomats were using sarcasm and colourful language as a diversion tactic. In his address to the security council Mr Nebenzia recited from Alice’s Adventures in Wonderland and compared the poisoning to the detective drama Midsomer Murders.

"Something is probably going to happen,'" Boris Karpichkov says his old friend told him. "It's very serious, and you are not alone."

LONDON — The former Russian double agent got a terrifying message on his birthday: He was on a Kremlin hit list along with Sergei Skripal, another ex-spy who weeks later was poisoned with a nerve agent in a case Britain blames on Vladimir Putin's government.

"Be careful, look around, something is probably going to happen,'" the former agent, Boris Karpichkov, says an old friend told him on the telephone in mid-February. "It's very serious, and you are not alone."

Also on the Kremlin's list, he says, were several other ex-KGB agents, as well as Christopher Steele, author of a 35-page dossier alleging collusion between Russia and the Trump campaign. Bill Browder, the driving force behind a set of U.S. sanctions against Russian individuals known as the Magnitsky Act, was there as well, he adds.

Karpichkov, 59, says that at first he thought the call was a joke rather than a threat — typically dark Russian humor. But Skripal's poisoning has put him on high alert. “Trademark FSB,” he says, referring to Russia’s security agency, the Federal Security Service, the successor to the Soviet-era KGB. NBC News interviewed Karpichkov over the weekend at a rented studio in London; he refused to say where he lives in the U.K.

Putin has denied Russian involvement in the Skripal case, calling the allegations “nonsense.”

What began as a spat between London and Moscow has snowballed into a chorus of international criticism of the Kremlin, with a series of governments ejecting dozens of Russian diplomats.

On Monday, the U.S. announced that it was expelling 60 Russians, which followed the U.K.'s decision to kick out 23. Russia’s foreign minister said on Thursday that Moscow would expel the same number of diplomats from each nation that has expelled Russian diplomats.

Karpichkov believes that the attack, if not directly approved by Putin, was at least authorized at the highest levels of the FSB. It was a “very planned, organized and performed operation,” he said.

The Skripals' poisoning, with the nerve agent Novichok, has sent chills through the large Russian expatriate community in the U.K. Defectors and Kremlin critics are particularly rattled.

An inquiry by British investigators concluded that his death was the work of the Russian state and was probably greenlighted by Putin himself.

Karpichkov was one of two former double agents who spoke with NBC News about their anxieties in the wake of the Skripal poisoning.

Victor Makarov, another former KGB agent, fears for his safety but lives in a much less guarded way than Karpichkov.

[above: click to view video]He invited NBC News to his small apartment in a public housing block in the sleepy northern England town of Haltwhistle. He considers the watchful neighbors and tight-knit community his best defense against any attempt on his life by Russian agents.

“If any stranger appears, he will be immediately seen, believe me,” says the 63-year-old. “I have two people on my side: God and the local community.”

Makarov now lives a modest life on a state pension equivalent to around $1,124 per month, but once seemed destined for greater things. He overlapped with Putin at an academy for aspiring KGB agents, although he has no memory of the future Russian president, he says.

Upon graduating, Makarov worked as a Greek-to-Russian translator in Soviet intelligence. He grew disenchanted with Soviet foreign policy after the 1979 invasion of Afghanistan and repression in Poland.

“My defection was caused by the fact that I realized I was doing the wrong things, serving this regime,” he says.

He approached a British spy in Moscow through an intermediary and, over a two-year period, passed information to U.K. intelligence. Makarov was eventually caught, arrested and sentenced to 10 years in a forced labor camp. His sentence was cut in half after the collapse of the Soviet Union, and he was freed in February 1992.

After his release, Makarov approached a British official in Latvia, who facilitated his defection to the U.K.

Makarov, now a British citizen, believes that Putin, resentful toward the West for “being ignored,” simply wants to be reckoned with. He “adores brinkmanship and intimidation,” Makarov says.
